TIPPING MACHNE.

Application filed June 7,

My invention 'relates to what is known in the art as tipping machines, or devices for attaching two sheets or sets of sheets of paper together along` one edge by pasting and pressing the edges together. These machines are chiefly used to attach a color insert or tip to a pamphlet or a. section of acatalog, commonly called a signature.

One of the objects of my invention is to provide a machine that will operate with greater speed and e'l'liciency than those at present in use.

Another object of my invention is to provide a novel means f-or'h'oldin'g a piece of material against a carrier after the grippers on said carrier have released their hold on the material.

Furthe'r objects'an advantages of myinvention will become apparent from the following description taken in connection with the accompanying drawings, in which Figure l is a diagrammatic view illustrating` 'all the essential 'elements of a device according to my invention.

Fig. 2 is a somewhat similar view of part of the machine showing the construction of as much of the mechanical transmi`s-- si'on associated With the machine as is not 'old and well-known 'in the art.

Th'e device according` to m'y invention comprises a pair of continuously Irotating carriers, 'mechanism for feeding sheets of pamphlet like Sections to said carriers, means for applying paste to the pieces on one of said carriers and mechanism for rec'eiving` vthe assembled units from said carriers. Synchronous stops and grippers are employed for bringin'g the two parts to be united on to said. carriers in properly cor related p'ositions, and vmeans for synchronizing 'the operation'of both feeding niecln anisins and of the p'aste applyingm'echanis'm are also provided.

Referring to the drawings and 11 indcate a pair of cylinders continuou'sly 'rotating in opp'osilte direc'tio'ns so that theirl adjacent port1ons move downwardly as infeeders indicated'as a' whole by the characters1'2and 13 are adapted to supply pieces 'of she'et like material `to the`c`a'rrife`rsv 1'0 and 11 respectively. A pair of s'tops 14 and 15 'are associated with the carriers 10 land 11 and ieach oa-rrier has ``two sets of gripp'ers 16 'and 17 respeetively. In the operation 'of 1928. serial No. 114,111.

my machine, a pamphlet like section or si'g; nature is automatically fed forward against the stop 15 vand the tip or insert is 'automaticall'y fed forward against the 'other stop 14. As theleading edges of the spaces for the gripper elements 16 and v17 pass Simultaneously under the Istops 14 and 115 cam me'chanisms swing these stops to one side and other` c'ams swing the gripping' velements quickly vinto operative position clamping the signature -anfd insert against their respective carriers. A paste foun'tain '19 maintains 'the surface of the paste roll 20 wet with paste and a blade 21 is adapted to receive p'aste from the roll '20 a'nd carry it down to v`apply it to the leading 'edge of the inser't 22. The blade 21 is geared to the carrie'r 10 for synchronous operation so that it will registei` with the leading 'edgeV o'f each insert. In the device illustrated each complete rotation of the 'carriers 10 11 comple'tes the p astng or tppn'g of two signatures, but itrwill be obvious lthat the carriers could be designed lto'h'andle 'any Ivdesi'red number 'of pieces in l'one revolution. h For 'this purpose ea'ch carrier is provided' with two sets of l1diam`et`i`ioally' oppose'd grippers 1'6l and 17 and the pas'te blade 21 and stops 14 and 15 are geare'cl to 'operate'throug-h twocy'ciles during a single rotaftion 'of the oarriers. In

the position illus'trafted -ifn Fig. 1, a signature v:box indicalted i'n' its entiir'ety by 'the reference 'ch'aract'er 27.` The p'aoling box ``contains a fork v28 adapte'd to Emovie frorn side to side Vas the successive units fall bes'ide it and push 'them into ftwo `oppo'sed pil'es 29.

As this 'form of receive: is 'old wellkno'wn in the art, furthe'r description'ther'eof appears unnfeoes'sary. v

It 'is necessary forA the ;insert grippe'rs 16 to 'be remo'ved out 'of the way of vthe signature i grippers 17H before the signature and' inser't frnake 'contact and it is of course falso vneoes`sa1`-`y for lthe signature Vgrip'- per's 17 to be mo've'd out 'of 'opferative position 'before the *stri'ppers 24renove the assembled unit from the `Varrier. The 'c'ains customarily employed for' these grippers are therefore cut so that the insert gripper 16 rotates back into the position indicated in Fig. llbefore the' carriers have brought the signature and insert into contact. To securely hold the insert in place on the carrierlO after the gripper 16 has been moved back, air ducts terminating at'the surface of the carrier 10 near the edge of the gripper space are adapted to deliver suction during the motion of the insert after the gripper has' been moved back and until the signature has been pressed against the insert.

The signatures' 31 are fanned out as clearly indicated in the drawings and the pile isV held in position by feet 32 which are automatically raised by cams at the proper time to permit the pusher33 to slide the uppermost signatureidown against the stop 15. 'For feedingithe inserts 34 which are too thin to he'ihandled by a pusher I have devised novel means for quickly sliding an insertat the 'proper time down against the stop 14. This means comprises a continuously rotating roller 35 adapted to be dropped at the proper time from the position shown in fulljlines in Fig. `1 tothe position in dotted lines,l to engago and' feed an insert down tothe stop 14. A suitable insert lifter and puller comprising a suction foot 36 and driven by cams to lift the next insert and move it forward under the r'oller 35 atthe proper time may be employed.

Referring to Fig. 2 in which I have illustratedthe novel details of construction involved in my invention, the carrier 11 by means of suitable sprockets 37 and 38 and a chain 39 drives a main countershaft 40 at twice the speed of the carrier.`` A suitable 'rocking leverV 41 mounted on a fixed pivot 42 carries a roller riding on avcam indi- `cated in dotted' lines at 43 and is adapted to operate the stop 15. The roller maybe vheld in contact with its cam 43 by means of a suitable spring 44. A pair of cams 45 `and 46 on the main countershaft 40 are adapted to. 'simultaneously operate the pusher-foot 33 and' thehold-down 32 raising the hold-down while the pusher-foot operates to slide 'the 'next signature into position.

The carrier 10 jby. a similar chain and sprockets drives i another main Vcountershaft 47 .carrying a vsimilar cam48 for Operating the stop 14 through the rock lever ;49. `A

shortstationaryshaft 50 carries bell crank levers 51 with rollers tadapted to engage suitable camsfi52 oii the main countershaft 47. The roller 35 is carried by the outwardly extendingarms of the hell cranlr` i levers 51 and continuously driven from the main countershaft 47 by asuitable train of -gearsas illustrated; Another vbell crank lever 53 pivoted on the shaft 50 carries the hold-down 54 which is also operated by a suitable cam 55 on the main countershaft 47. The lifter and puller comprises an arm 56 pivoted at 57 and a downwardly extending arin 58 terminating in the suction foot 36. i

A pair of cams 59 and 60 on the rotating shaft 61 engage suitable rollers on the arms 53 and 56 respectively. The shaft 61 may he driven by` any'suitable means, such for instance, as a sproclret Vchain (not shown).V from shaft 47 or 50. In Operating .the lifter and puller, the cam 60 will move out from under its roller and lower the foot into position and immediately thcreafter the cam 59 will move away from its roller vand spring 62 will pull the upper insert forward under the roller 35. I have illustrated suitable gears 63, 64, 65 and 66 for driving the paste roll 20 and the paste blade 21 from the main countershaft 47. A suction tube 67 with suitable ports may he used to de-` liver suction to the ducts 30 during rotation `through the arc indicated by the arrow 68.

it should be clearly understood that the description is only for purposes of illustration, that devices according to my invention may bo used forhandling a'large variety of materials other than those referred to andt-hat many variations and modifications will naturally occur to-those skilled in the art. I aim in the subjoined claims to cover all such` legitimate modifications and Variations. z
